Control Chart Confidence Interval

Question & Answer

1

Good afternoon,
I saw a video in Tableau where someone builds a control chart to include the confidence intervals and the average line. From the screenshot below, the confidence interval is 95%.

In QuickSight, I added the average line with a reference line. When I tried to include the confidence interval with a reference line, I saw that there is the option to choose the percentile value but not the confidence interval. Is it possible to include the confidence interval?
Thank you,

Currently you can only do a percentile value.

I can mark this as a feature request.

Good afternoon Max,
Thank you so much for the response. In the future, it would be great if the confidence interval can be added as a feature.

Iā€™m wondering whether I can achieve the same result by doing the following: creating a calculated field for the confidence interval, and adding a reference line with the calculated field. I will try it and see what it gives.

Have a great day
